The ATNF Visualisation software is a suite of tools (outside Miriad) designed
to display images and data cubes (including Miriad images and cubes). See
Chapter 3 for more information.

The main visualisation tool of interest in image display is kvis.
This tool allows you to inspect one or two 2- or
3-dimensional datasets in several ways. The simplest thing to use it
for is displaying a dataset. kvis
supports flexible zooming, special colour
maps for velocity fields etc. For 3-dimensional datasets one can play
the channels - as well as the RA-VEL and DEC-VEL slices - of the data
cube as a movie, in order to get an idea of the 3D structure of the
emission in the data cube.

kvis can load two datasets, which can
then be viewed simultaneously in several
ways, eg. blinking, or by displaying one data set as contour levels on top
of the other. The
advantage of kvis is that one has interactive control over
zooming, contour levels etc., so it gives more flexibility than
e.g. cgdisp. This mode of kvis can be used for
overlaying a radio-continuum map on an optical image, or the channels
of an HI data cube on the continuum or an optical image and inspecting
this interactively. Note that for the contouring, the two datasets do
not have to be on the same grid, although they should have a proper coordinate
system defined. Also note that the visualisation software can read
data in FITS format so one can load images from e.g.
skyview
directly and overlay Miriad datasets.

kvis can also produce full colour postscript output of whatever
you display.
